Good article on Sigma Labs and Los Alamos on 3D Printer-World

Quote from Mark Cola...
" Los Alamos National Laboratory was one of the first research institutions back in the late '80s to work on 3D printing of metals. Los Alamos invented and was awarded a patent for, the Directed Light Fabrication (DLF) process which later became the Laser Engineered Net Shaping (LENS) process at Sandia National Laboratories. Some of the founders of Sigma Labs were actually responsible for helping to bring LENS to life, and so we've been technically involved with 3D metal printing right from the very beginning."
Research at Los Alamos is government-funded, a plus for SGLB shareholders also IMO.
Gary, i would suggest that MHTX is also a 3D stock for your blog to cover. Like SGLB, they have a business side that has nothing to do with 3D, but their current bill-paying technology is metal powders, which they supply to Carpenter Technologies on a license/royalty basis that pays MHTX's entire operating cost. Incidentally, SGLB and MHTX are old friends from the Los Alamos days, and they have a partnership for dental implants. Well worth looking into, imo.
